To all whom t may concern: Y

Be it known that I, GILBERT S. Enni- 'rnonrn, a citizen et' the United States, residing at Chicago, in the county of Cook and State of l'llinois, have invented certain new and useful improvements in Shoe- Heels, of which the following is a specification.

My invention relates to improvements in shoe heels and has especial reference to heel lifts and inherent means for securing them to the shoe.

One of the objects of my invention is to provide a shoe lift, preferably composed of a resilient, moldable material, such as rubber or the like, and attaching means resident therein, whereby the lift may be secured to the heel of the shoe by unskilled persons and without the use of separate brads7 screws or other attaching instrumentalities.

Another object of my invention is to provide la shoe heel or lift having a Vflat area, or zone within the region of which the attaching means is located and a surrounding marginal edge or portion laterally deiiected at a suitable angle to provide a pseudo concave-convex inner and outer surface whereby to exert a resilient stress upon the edge of the lift to hold it in intimate contact with the contacting edge of the shoe structure, while, the center zone is at all times fiat.

Other and further obj ccts of my invention will become readily apparent to' persons skilled in the art, from a consideration of the following description when taken in coujunction with the drawings, whereby#- Figure l is a central section of the lift taken on line l-Il of Fig. 1.

liig. 2 shows a similar section of the lift after it has been applied to a. shoe.

Fig. 3 is a plan View of the underneath or tread side of the lift, showing parts broken away to expose the upper surface of the attaching device.

Fig. -l is a cross section of one forni of attaching device; and

ln all the views the same reference chan acters are employed to indicate similar arts.

',llie heel or lift 5, is

made of ino l;

and, preferably, resilient material, such as rubber or the like, and is provided with a fiat central outer surface and a parallel fiat lcentral inner surface 7 with downwardly or laterally deflected surrounding edges 8 and 9, thereby to provide a partially concave surface 10 and a partially convex surface l1, and when the lift in place on the shoe, the surface S is substantially parallel with the surface 6, as shown in Fig. 2. The attaching device 1.3 is provided with a flat upper or head portion 1G, which lies between the flat surfaces 6 and 'Z of the lift. In the particular showing the device 15 is provided with three downwardly projecting prongs or. brads 17, which taper gradually, preferably, to a relatively sharp point 18, from each of its sides, the bradsbeing held together by a rim 19, which is an integral part of the structure. rlhe brads have chisel points, being preferably sharpened from the inside surface, as at 20, so that when the brads are drivenl into the lift of the shoe, they will be deflected laterally, as shown in Fig. 2. The outward turning of the brads is produced by the peculiar manner in which they are sharpened. The chisel edge is in the salue vertical plane as one edge of the brad, and therefore when the device is driven, by the application of a hammer to the fiat surface 5, the brads will take a lateral course from the perpendicular, as soon as they enter the, lower leather lift lai of the shoe heel, and continue in such path as shown in Fig. L), until the heel lift 5 is in proper position on the. leather lift of the shoe, thereby rendering the device difficult of removal, without breaking the attaching means. l may place the outward projections Q2 and inward projections upon the device l5 to prevent it from turning in the lift 5 and to give the attaching brads 17 more superficial contact with the material in which they are embedded.

il have shown a modilication l5 in Fig. 5 of the device shown in lrig. i, in which the brads i7 are serrated ou their edges, as at 25, so as to make them cling more tenaciously to the substance through which they maybe driven in applying the. lift to the shoe.

(lne of the important features of my in vention is the permanent association of the attaching device with' 'the lift, and :mother important feature of the invention is the joining together of the brads ai riching means 17 at or near their upper ends, so

that they will not be initially inclined outv of a true perpendicular'at the time when they are being driven into the substance of the shoe heel, in the act of attaching the lift to the heel.

While I have herein shown but two embodiments of my invention for the purpose of clear disclosure it is manifest that changes may be made in the general arrangement and conguration of the parts within the scope of the appended claims.

Having described my invention7 what l claim is 1. A tread lift of resilient material having a tread face provided with a relatively flat central 'portion and deflected marginall portions, .and a body portion concave-convex in transverse section, the forward edge or breast portion of the lift having curved upper and lower edges, and fastening means embedded in the body of the lift within ythe central portion located and arranged to exert a substantially equal pressure coextensive with said central portion.

2. A tread lift of resilient material having a tread face provided with a relatively flat central portion and deflected marginal portions, and a body portion concave-convex both in longitudinal and transverse 'section and bounded by curved upper and lower edges, and fastening means embedded in the body of the lift within the central portion located and arranged to exert a substantially equal pressure coextensive with said central portion and partly projecting therefrom to secure the lift to the shoe. p 3. A heel lift comprising a body of resilient material of concave-convex form and having a substantially flat central tread sur-r face area and laterally deflected margins of substantially uniform thickness bounded by curved upper and lower edges, and attaching means embedded within said l'iat central portion located and arranged to exert a substantially equal pressure coextensive with said central portion. f y

fl. A cushion heel lift, comprising a resilient body, the upper and lower faces of which are mainly concave and convex respectively, the central portion of said body being of substantially circular flattened form, and fastening means embedded in the body of the lift Within the central portion located and arranged to exert a substantially equal pressure coextensive with said central portion.

5. resilient heel lift of concave-convex shape and being centrally fiat, the upper and lower surfaces of vwhich coincide with the respective surfaces of revolution of a pair of lines intersecting the vertical axis of said lift, one above the other, said lines being straight and perpendicular' to'said axis adjacent to the lat-ter to a certain point, and divcrging therefrom downwardly and' out`l wardly to the edge of the lift.

In testimony whereof l. hereunto set my GLBERT S. ELLlTH-OBPE.
